The sun rises at 07:45 and sets at 17:59 in Arvayheer, Mongolia today, giving 10h 14min of daylight.
Sunrise and sunset are calculated from the city's latitude and longitude together with the sun's declination for the date, following the NOAA solar position algorithm. Because the calculation depends on position rather than on a fixed table, times stay accurate as the year turns.
Why the times drift
- Day length changes fastest around the equinoxes — up to 2-3 minutes a day at mid latitudes — and barely at all near the solstices.
- Latitude decides the range: the closer a city is to a pole, the wider the swing between midsummer and midwinter.
- Times are local clock time and already include daylight saving where it applies.
